Thu, 26 Apr 2018 16:25:05 +0000https://www.internationalgasdetectors.com/?p=2466Is my swimming pool a safe place? With many Chlorine related incidents being reported in the press this can be a real issue for both pool operators and swimmers. In August 2017 a malfunction with a machine caused chlorine to leak into the pool whilst the pool was being used, luckily no one was hurt....

Do I Need Chlorine Gas Detection For Swimming Pools?

If you operate a pool how do you take steps to really ensure swimmers are kept safe from Chlorine hazards? Fitting a Chlorine gas detection system seems like a logical choice but with lots of choices, choosing the wrong system can become expensive very quickly. Installation costs can often be much more than the initial equipment costs. Chlorine can be a difficult ‘on site’ calibration so maintenance costs can quickly spiral.

IGD’s Cost effective Solution For Your Gas Safety

IGD’s TOC-625 Micro gas detection system is increasingly becoming the first choice for this type of application. With no hidden extra’s TOC-625 Micro is the ideal small system for a whole range of applications.

By using the plug and play version of the system, operators can use their own maintenance staff to install the system. IGD can provided backup support to ensure detectors are placed in the most effective locations. Chlorine gas detectors are delivered pre-calibrated and will operate to specification on power up. IGD’s Sentinel® communications protocol ensures devices remain correctly connected and operate within limits. With plug and play detectors there are no wiring errors and all 8 devices are on a single cable run.

On power-up the TOC-625 micro system asks the user if they are ready to self-discover connected devices. The system then auto detects all devices connected to the controller and automatically sets channel displays and alarm levels. This allows plant operators to deliver an ‘on budget’ safety system without any compromises.

For ongoing maintenance, the system should be calibrated at least once a year. Chlorine gas detection systems can be calibrated by exchange rather than requiring costly site visits. As the settings are saved on the detector heads, you can easily swap the front of the detector for service and replace it with a new sensor from IGD with our exchange deal. A simple and cost-effective solution for a difficult challenge.

Finally, with IGD’s Sentinel® protocol, the protocol continuously monitors the system performance. The 625 MICRO control panel has a colour changing display (green for safe and red for alarm) with clear messages displayed on screen. The system also cycles through all current gas levels, for connected devices, giving you a clear unambiguous display. Every event is reported to the panel immediately, with a clear message on the panel display.

For any questions, advice or support regarding your pool gas safety, or for larger systems that require more than 8 sensors, email our team at: sales@internationalgasdetectors.com or speak to one of our experts on: 0161 483 1415.

]]>At IGD we are often asked by prospective clients if they really need a gas detection system and if so how does it fit into their risk mitigation scheme. Whatever the facility and activities being undertaken, risk assessments will be undertaken to analyse risks and evaluate how to eliminate and minimise them. Methods and approaches to do this are well documented with many standards, guides, codes of practice and courses available. Yet still risk assessment and mitigation can be a minefield particularly when your main role is the management of a facility and your background is a completely different discipline. This article does not set out to repeat what has already been written by others. For an approach to risk assessment the best starting point is the HSE website which provides sound guidance and best practice. Our aim with this article is to consider the role that gas detection plays as part of an overall safety scheme.

Functional Safety Overview

When considering your facility and assessing risks you will consider if processes have to be undertaken and if materials have to be used. If so then control of the process and materials in a safe manner will be of paramount importance. As far as gases and vapours are concerned there are three basics to consider.

Flammable Gas Hazards

For flammable gases DSEAR regulations state that ‘no atmosphere should be above 25% of the Lower Explosive Limit where flammable gases or vapours are in use or could exist’. So if the facility uses or could generate flammable gases or vapours how you prove that will need to be considered.

Toxic Gas Hazards

Toxic gases will usually come under COSHH regulations and as such will be listed on the HSE’s document reference EH40. If the material has an EH40 listing then occupational exposure limits will be detailed. Another information source would be the Material Safety Data Sheets provided by the supplier, again these will list any exposure limits. Where exposure limits are listed you will need to consider how to show compliance.

Asphyxiant Gas Hazards

Asphyxiants are dealt with a little differently. Here the material is perhaps not flammable or directly toxic but will work to reduce Oxygen levels. Here the British Compressed Gases Association produce guidance note GN11 which states ‘that no-one should be exposed to an atmosphere with an Oxygen level lower than 19.5%’. Again you will need to consider how to demonstrate compliance.

Gas Detection’s Role and the Functional Safety Gap

In conformity terms if your not monitoring your atmosphere then it will be hard to demonstrate compliance. This is one important area where gas detection plays a vital role.

Whilst considering your obligations one question we are continually asked is if industry guidance notes and Approved Codes of Practice need to be adhered to, if they are not actual standards or legislative documents. If you adopt the advice from an ACOP or Guidance Note you will be doing enough to comply with health and safety law.

If you are prosecuted for breach of health and safety law, and it is proved that you did not follow the relevant provisions of the Code, you will need to show that you have complied with the law in some other way or a Court will find you at fault.

Health and safety law applies to all, there are no special exclusions for size of company, educational or recreational establishments or sectors.

Figure 1: Gas Safety & The Role Gas Detection Plays

So in terms of health and safety when considering risk mitigation then with reference to fig 1.

If you do nothing then you have 100% of the risk you have identified. Your control of process to mitigate risk in terms of interlocks, ventilation automated shut off systems and such, will work to lower the percentage risk. Safe operating procedures training and PPE will then provide further risk reduction. After these steps have been undertaken there will be a safety gap which will need to be reduced in order to achieve an acceptable risk level. This is where gas detection fits into the safety scheme to act as a backstop to all the other risk mitigation techniques.

As we state earlier if you not monitoring your atmosphere you will not know if you have any issues and you will not be able to alert in response to hazards should other mitigation fail.

Gas detection is never a primary safety method but always acts as an overall backup to primary mitigation methods.

Placement and type of detectors will be key to effective monitoring as illustrated in fig 2. Remember that the detectors are reporting the gas level in their location, significantly more dangerous levels can exist closer to leak sources. To be effective gas detectors will require regular calibration or calibration checks. Modern systems can be used to not only alarm but also provide automated reporting for self checking and event monitoring. Leveraging this data from a system provides an effective means to prove compliance to health and safety legislation.

At IGD we are often asked for room entry status indicators to show if it is safe or not to enter an area protected by our gas detectors. In many cases clients will ask for some kind of traffic light arrangement to ensure nobody walks into a hazard.

IGD have a simple approach to protecting environments. If we have gas detectors in an area monitoring the environment then we will have beacon sounders, clearly labelled to evacuate that area on alarm. Once evacuated we want to ensure people don’t re-enter an environment that may be unsafe. IGD’s range of room status indicators provide a novel approach which is clear and unambiguous, a key requirement.

The status indicator uses a two-line colour change display. Green when all is OK and flashing, red when its in alarm. There is a customisable display, featuring a two line message. By default the green display will message OK TO ENTER and the flashing red display will message GAS ALARM. Furthermore, should a fault occur the display will change to yellow and display FAULT. Clear messages, easily understood by all. In addition the unit has an 85dB sounder. Placed at eye level by a doorway the unit clearly indicates the room status.

However the unit can do much more than that:

The display can be programmed to indicate the readings from up to 8 detectors/devices on the same addressable cable highway. This means that the room status indicator can sequentially show up to 8 gas detector readings. IGD’s Detector nodes interface to standard 4-20mA detectors. Furthermore temperature, pressure and flow probes, with a 4-20mA output appear on our room status indicators. More than this, the status indicators also have relays and digital outputs included allowing them to run additional illuminated signage, beacons, solenoids or door controls to further enhance site safety and leverage more benefits from your investment. This however is not all. Room Status Indicators, fitted with slam switches or key switches, create extra flexibility for process laboratory areas or similar applications.

IGD’s room status indicators provide an innovative solution to a number of common problems, clearly displaying local information and alarms in a simple yet powerful format.

Introduction:

Unlike fire systems that have a specific standard for installation and placement, EN54, there is no similar standard that exists for gas detection. Gas Detection systems only have industry approved best practice guidance notes for locating, placement and number of gas detectors. This is due to the complexity/speciality of gas detection due to the vast amount of gases being detected, over 400 gases with varied amount of properties and environmental influences factors, such as heat, that affect gases in different ways.

The following article is intended to bring together UK industry legislation and guidance notes, to help advise you with the consideration and placement of IGD gas detection systems. Furthermore this article also helps with the different solutions that IGD has for gas detection, for example the use of our Addressable Sampling Systems, ideal for hard to access places or where traditional detectors would not work; examples could be Clean Rooms (Please see our case study for Sampler Systems). Finally this article also highlights the importance of effective maintenance of your gas detection systems by engineers who can demonstrate competency of the system; through training and certification. When contracting a company to undertake the management of the gas detection system, ensure that this is part of the scope of their ISO 9001 quality system.

Gas detectors are usually categorised into three distinct groups for placement:

Plant Protection

Flammable gas detectors are typically categorised into this group. Besides asphyxiation, flammable gases are generally not directly toxic and therefore, the strategic position of detectors is where the gas is expected to accumulate based on its relative density to air (heavier or lighter).

Process Monitoring

Typically gas detection systems in this section are used to monitor and either alarm or be part of processing control. This could be monitoring VOC (Volatile Organic Compounds) levels pre and post filtering, Solvent Vapour (LEL) monitoring in drying ovens, Ventilation control in Car Parks and building etc. Location of these detectors will usually be based on the individual application, after considering the process, gases or vapours, air movement and temperatures involved. Applications falling into this category usually need a good dialogue between IGD and the plant designers to ensure the best placement of the detectors for them to be highly effective.

Life Safety Systems

In such systems, the concern is that an asphyxiant or toxic gas is directly hazardous to personnel. The position of the gas detectors is based on the normal operating zone for people in the area of application. It is worth noting at this point that there maybe two sets of detectors involved with a life safety system. The first set of detectors perform as a process monitoring function, with the detection based on the relative density of the gas with respect to the air. This set of detectors is typically used to perform some type of function, for example: bringing on extra ventilation to clear a spill hazard.

The second set of detectors are in the ‘life safety or breathing zone’ and alarm for personnel protection. When planning the system, careful consideration needs to be given to the actual setting of alarm levels for the detectors. In general HSE document EH40 lists hazardous gases and vapours and safe occupational exposure limits. IGD base our alarm recommendations on the published figures provided by EH40. Where a detector is fitted into the breathing zone for a gas, which is much heavier than air, then the alarm level is set at a lower level to offset the effect of the higher location.

A typical example would be a Liquid Nitrogen Dewar fill room. In this application we know that spills will occur as Liquid Nitrogen is decanted. In this application the Low-Level Oxygen detectors bring on extra ventilation at ground level to clear the Nitrogen spill as it evaporates into the atmosphere. If the ventilation cannot effectively clear the spill, then the detectors in the breathing zone are used to alarm and evacuate personnel in the area, until such time that the atmosphere returns to normal safe levels.

Specialised Sampling Gas Detectors

As well as manufacturing diffusion based fixed gas detectors, IGD also produce a range of sampling gas detectors. These are utilised where it may be difficult or impractical to use a standard gas detector. Typical applications could be: hard to access areas due to height, accessibility or detector size; clean rooms; where it is desirable to minimise surface areas inside the facility. IGD’s sampling gas detectors are addressable modules that can be fitted alongside standard diffusion type detectors. These sample modules operate continuously using IGD’s piezo pump technology. This technology has virtually no moving parts for enhanced reliability over standard pumps. In addition, the units can be set up to continuously check and correct their zero or calibration point (depending on detector) by drawing a clean filter air sample through a separate port. A diffusion based detector directly in the area of interest is always the best option, where it is required IGD’s sampler modules offer an excellent alternative solution. You can read our article on why IGD don’t recommend replacing gas detectors with samplers unless necessary.

Cryogenic Gas Detection

Careful consideration is required for gas detection for applications involving the use of cryogenically cooled gases such as liquid helium or nitrogen. On initial release, cryogenically cooled gases can typically have a lower temperature and higher density compared to their surroundings and therefore, they will have a different behaviour than their gaseous state. In this instance it should be considered for two sets of detection for optimal safety, one for low level detection in the gases cooled state and one for the life safety zone. It is recommended to survey applications involving such gases.

Area Coverage for Gas Detectors

Like smoke detectors, a gas detector is capable of providing up to 75SQM area coverage based on a 5M radius of operation. There are many factors affecting this, ventilation air flows, gas characteristics, equipment in the area, geometry of a room etc. IGD can provide support throughout the survey, design and installation process to ensure the best possible result on site.

Calibration and Service Requirements for Gas Detection Systems

Regular checking and calibration in compliance with the UK factories Act 1961 and BS EN 60079-29-2:2007 (in the near future Toxic Gas Detection will have a legal requirement to be serviced on a regular bases) is required for all gas detection systems. The service and calibration period will be a function of the application based on environmental in-service conditions. Both IGD and BS EN 60079-29-2:2007 legislation states that gas detection systems must be serviced every 6 months. Furthermore, the PUWER 1998(Provision & Use of Work Equipment Regulation) states “safety equipment needs to be effective and maintained”. With these Acts/Articles in mind, it is essential to ensure that a service plan is in place for any gas detection system deployed as part of a site safety system. IGD can work with operators to offer advice, service and spares to ensure an appropriate level of cover.

Gas Detection Service Engineer Competency

IGD run an approved gas detection engineer training scheme and strongly recommends that only IGD certified engineers who have passed the IGD Engineer training scheme should service and calibrate IGD equipment. IGD offer 12-month or 24 Month service contracts (2 service visits a year). IGD certified engineers will carry the below emblem with a unique number, please consult IGD for proof of competency.

Siting System Components

Control Panels

Control panels should be positioned outside of the hazardous area, protected by their connected gas detectors. They should be accessible such that when an alarm is triggered, it should be possible to evacuate the area and view the gas levels from the controller.

Audible Visual Alarms

As a general rule, if there is a gas detection fitted to an area then there should be an audio-visual alarm (beacon sounder) to alert personnel who may be in the same area. Audio-visual alarms are typically standard beacon sounders where the sounder can be silenced from the control panel once an alarm is accepted. IGD offers Standard LED beacon sounder modules, which can be operated from addressable I/O points to minimize cabling. Fitting IGD’s range of annunciators is the other option available.

Annunciators

Annunciators are addressable devices usually installed at door entry points. In the event of a gas alarm, a clear audible visual alarm is provided by an annunciator to warn people from entering an area where a gas hazard could be present. Annunciators are advantageous in many ways when compared to standard beacon sounders. They can be installed on standard dado trunking systems; cannot be confused with other alarms; can be fitted with slam switches; and the displayed alarm message and flashing colour display are unambiguous.

Gas Collector Cones and Splash Guards

Gas collector cones can be considered for use in areas where detectors are placed above gas plant such as boilers or meters in rooms with high ceilings. They are fitted to detectors located just above gas plant to enhance the capability of detectors to sense gas leaks.

The Problem:

When West Herts College came to International Gas Detectors (IGD) with a need to monitor for flammable gas leaks in their craft room, a fairly straight forward requirement on paper. As it turned out the challenge was not technical but rather costs. Similar to many educational and similar clients, West Herts had the budget for the equipment or the install but not both. Fortunately for West Herts College IGD had a novel solution.

IGD’s Gas Detection Solutions:

IGD’s TOC-625 Micro gas detection system is the perfect choice for exactly such applications. This system is based on IGD’s proven gas detection technology. The system caters for up to 6 gas detectors and two relay output modules. Critically for West Herts the system is produced in two versions. TOC-625 Micro can either be conventionally installed or is available with pre-made cables allowing the system to be literally plug and socketed together.

By using the plug and socket version this allowed the college to use their own maintenance staff to install the system themselves. IGD provided backup support to ensure the detectors were placed in the most effective locations. The college maintenance team then installed two detectors (one high for Acetylene detection and one low for LPG detection) a relay module with beacon sounder and controller themselves.

The Result:

On power up the TOC-625 micro system asks the user if they are ready to self-discover connected devices. The system then auto detects what modules are connected to the controller and automatically sets channel displays and alarm levels. Detectors are delivered pre-calibrated and will operate to specification on power up. IGD’s Sentinel communications protocol ensures devices remain correctly connected and operate within limits. With plug and go detectors there are no wiring errors. This allowed West Herts college to deliver an ‘on budget’ safety system without any compromises.

Test gas aerosols are also available allowing users to carry out periodic spot checks to ensure correct continued operation. The college has since extended gas detection into other installations on the site.

Easy integration to other systems using built in Modbus interface, BMS, Fire etc

ATEX or safe area versions

Use IGD’s 100 years’ experience in gas detection with a host of accessories, adaptors, and knowledge for all applications

Puts Control Where You Need It Without the Extra Install Cost

2-Wire technology using IGD’s Sentinel+ protocol is the next step forward in gas detection. Developed by IGD and building on 100 years in gas detection these new 2-Wire systems are fast to install, flexible to specify and offer benefits to the end user. All controllers have reporting capabilities to aid site safety management. IGD’s new Android apps make data gathering simple and speeds up servicing. Sentinel+ is a smart system protocol, continually monitoring not just gas levels but also system performance.

These systems offer major benefits to specifiers. When specifying detectors you are automatically specifying i/o capability. This means you are never under specified. Need another output for an audible visual alarm? Just connect it to the nearest detector. Need an output for a gas valve? Just connect to the nearest detector. Need to add a slam switch or break glass? Just connect to the nearest detector. Want to see what is going on inside a lab? Use an annunciator to display gas levels. Need to monitor for high roof spaces? Use a 2-Wire sampler module and tube up to the roof space. Gas detection made simple.

These systems offer major benefits to installers. All devices connect using 2 Core cable. The two core cable has no polarity requirement. This make installs faster, cheaper and with far less chance of cable errors. If installation requirements change then its easy to use the detector nodes I/O capability to add extra beacon sounders, signs, gas valve interfaces and controls.

These systems offer major benefits to end users. With built in reporting capabilities you don’t need a service engineer to tell you it’s all working correctly, sensor check reports do that for you. How do you know what’s been happening when, our built in event logs automate your site safety log. With blue tooth interfaces, use specific apps to download event logs, sensor check etc without having to interact with the panel interface, simple and efficient. leverage information from your investment.

With benefits through all stages of the system life cycle these new gas detection systems from IGD are detectably better.

Recently one of our directors got involved in a discussion on the Gas Detection professionals LinkedIn Group regarding a member’s concern for sample points, and felt the comment was worthy for further explanation.

The concern was should you utilise detectors with sample pumps?

In general terms, the answer to this question is no. Anything that comes between the detector and the hazard introduces the potential for unreliability and consequent detection errors. At International Gas Detectors, we would always try to deploy diffusion based sensors directly into the area of concern. This is by far the most reliable method. In some instances, this is not possible and at that point we consider the use of sampling gas detectors.

IGD’s Concern:

Currently we are fitting out six Gene Therapy Modules for a client. These are highly sterile environments which are regularly fumigated. Normal diffusion based gas detectors could not be used. The client wanted to minimise equipment in the modules to limit the potential for bacterial traps. Extracting a sample for gas detection was the only solution.

Many sampling gas detection systems sequentially sample to a common detector. On systems with many detection points this approach can lead to long cycle times. Take the example of a system with 10 sample points and a 2-minute sample time at each point. The cycle time is 20 minutes meaning 9 out of 10 ports won’t be sampled for 20 minutes.

The Solution:

IGD produce both addressable sample pumps and addressable 4 port samplers. This negates the problem of long cycle times. If the application is critical then use a point sampler where the pump/detector is dedicated to just one sample point. In less critical applications, a 4 way addressable sampler only ever has a maximum of 4 ports to sample around, minimising dead time.

In addition, IGD’s Piezo pump technology has virtually no moving parts. Many sampling systems have a multiplicity of pumps, filters, valves etc as part of their make up all with associated seals and wear parts. IGD’s samplers use piezo pump technology, no seals, wear parts, valves or diaphragms to maintain. IGD’s samplers are virtually maintenance free and self-monitoring.

The samplers employed by IGD extract their sample through IGD’s unique gas sample port. This is fitted through the wall minimising the impact inside the clean room. The sample port is available with a luer fitting allowing standard anti-bacterial filters to be fitted in normal operation. In addition, this allows the ports to be ‘capped off’ during fumigation.

In this application IGD located all sampler modules local to the sample points. 60 samplers were fitted all networked using our Sentinel+ addressable highway technology. Each sampler has very short sample lines, local flow monitoring and the capability to self-zero or in the case of Oxygen detection, self-calibrate.

‘The system has reduced cost compared to sequential samplers’

One of the biggest wins for the client; the system has reduced cost compared to sequential samplers and utilising IGD’s novel Piezo samplers there is no conventional sample pump, no solenoid, no moving parts with equipment providing over a 5 year lifetime.
